This paper deals with an experimental study on the local factors of friction in tangential direction and mass transfer coefficients on the wall of an agitated vessel with paddle type impellers as agitators, and with a discussion of the analogy between momentum and mass transfer phenomena. Experimental results show that the average factor of friction and j factor of mass transfer are correlated the same equation with respect to Reynolds number, and that the vertical distributions of local factors of friction in tangential direction and those of mass transfer coefficients are quite similar. Besides this it is found that the peak of the distribution curve at the height of the impeller is caused by jet flow issuing from the impeller, while the flat part of the curve is attributed to rotating flow. Finally the measured values of the local mass transfer fluctuation intensity were plotted in a diagram.
